Whether you know them as “puffies” or “puffers,” nearly all lightweight, insulation-filled jackets share a few key characteristics. These layers are defined by thin nylon/synthetic shells and insulation-filled baffles. Puffy jackets are a cold-weather staple, and advances in design have been incremental for decades.
Ibex’s Wool Aire Puffy Jacket ($285) is different. Instead of down or synthetic fibers, its face fabric is filled with tufts of merino wool. Ibex has been making the Wool Aire for over 10 years, but it remains novel among its homogenous peers. I tested the latest version over dozens of winter days and chilly adventures for a full season, and it held its own against all synthetic and down puffies in its price range.
In short: At 11.375 ounces (men’s medium), the Wool Aire holds its own against high-end, ultra-technical down-filled jackets. The gold standard for ultralight puffies is the Mountain Hardwear Ghost Whisperer, which weighs 8.5 ounces in a men’s medium. For neurotic thru-hikers, this difference may be significant, but most people won’t notice. For the majority of us, value is a greater concern than shaving 3 ounces. At $285, the Wool Aire is $40 cheaper than the Ghost Whisperer. Ultimately, the Wool Aire is slightly heavier and slightly cheaper than its direct competition, but its soft face fabric and breathability provide unrivaled versatility.
